This blog post focuses on the day and a half we spent in San Luis Obispo County. The tree of that leg of our trip was clearly Quercus agrifolia from the champion Ancestor tree at the Halter Ranch Winery to the pygmy trees of the Elfin Forest in Morro Bay.

A Conversation about Quercus ×turneri

Quercus xturneri

Did you know that Turner's oak occurs in the wild? Allen Coombes and Giles Crisp, members of the International Oak Society, discuss this popular hybrid in an interesting "tree conversation."

New Look for the IOS Website

New IOS Theme 2018

After moving it a month ago, we now have re-looked our website, making it fully responsive.

IOS Website Has Moved

We moved our website to A2 Hosting's data center in Michigan on Friday. The migration went very well. Unfortunately a technical incident, issues with A2's DNS Services, prevented us to go live. These issues were solved on Monday evening and the site is now accessible at its new location. See here: https://a2status.com/incident/564

The Hidden Hawthorn Society

I have always suspected that there was a secret hawthorn society hiding within the IOS. Last weekend, the Belgian Dendrology Society held a full-day event devoted to Crataegus. Three past and current Presidents of the IOS attended the meeting.

What is the Society's Actual Inception Year?

In the last days of September 2015, I visited La Closerie du Rond-Chêne and its oak collection, in southern Belgium, with past IOS President, Eike Jablonski. It was just a couple of weeks before the 8th International Oak Society Conference at The Morton Arboretum. So we were talking about the Conference when the conversation deviated to when the Society was really founded. Twenty-one years earlier, the IOS had held its first Conference, also at The Morton.

Quercophiles Abroad

Dan Keiser will be showing his IOS documentary, covering 20 years of traveling with the Oak Society, in New Richmond, Wisconsin on the 21st of February.
